that difference represents a deficit of $1.1 trillion. so you can see we are very close to being at a 60 year high in spending, and very close to being at a 60 year low in revenue. so i would say to those who say we just have a spending problem, i think you got that half right. i think we've also got a revenue problem. that needs to be addressed. let's go to the next slide if we can. the result of these deficits and debt is that we now have a gross debt that is more than 100% of our gross domestic product. you can see right in the middle of that graph, in 2012, the gross debt of the united states has now reached 104%. why does that matter? the best academic research, a book by rogoff of harvard, reinhard, the university of michigan i think she was when she did the study, look at 200 use of economic history. and concluded once you get a gross debt of more than 90% of your gross domestic product, your future economic prospects are dramatically reduced. future economic growth is reduced anywhere from 25 to 33%. so these are not just numbers
